REE-Bearing Cambrian-Ordovician Episyenites and Carbonatites in Southern and Central New Mexico, USA: new paper co-authored by several bureau researchers

Brick-red, K-feldspar-rich episyenites and carbonatites are found throughout New Mexico that contain anomalous concentrations of rare earth elements. Modern technology increasingly relies on rare earth elements (REE), which are now considered as critical minerals. This new paper discusses the geololgy, geochemistry, and gechronology of these important and interesting rocks.
